WATER-GAGE.

Specification of Letters Patent.

Patented Jan. 26, 1915.

To all 'wlz 0m it may concern:

Be it known that I, LEOPOLD KASSANDER, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in VVater- Gages, ofwhich the following is a specification.

This invention relates to water gages adapted to be used in ascertainingthe level of the water in steam boilers, and the like, and its noveltyconsists in the construction and adaptation of the parts as will be morefully hereinafter pointed out. In instruments of this class it isdesirable that the thoroughly protected sight glass should be frominjury and at the same time, danger of leakage should be avoided, andthe descrlbed invention secures these desired ends efliciently and witheconomy.

, In the drawings, Figure 1 is a front View of a device embodying theinvention; Fig. 2 is a central vertical section thereof, and Fig 3 is atransverse horizontal section on the plane of the line 3-3 in Fig. 1.Fig. 4. is a detail perspective view of certain of the compressionmembers and a portion of the ring on which they are mounted.

In the drawings, 10 is the sight glass made of glass of usual form anddimensions, 11 is a casing made of suitable material as cast metal andprovided with a vertical channel or recess 12 adapted to contain thecolumn of water the height of which is to be ascertained.

13 and 14 are pipes or fittings secured to, or made integral with, thecasing 11 and affording communication between the channel 12 and thewater space of the boiler. The casing 11 is provided with two walls orside members 15, 15, the space between which is wider than the width ofthe sight glass 10 and terminating in a plane 16 slightly in front ofthe front surface of such'glass. In front of the walls 15, there isarranged a cover plate 17 having a long central aperture 170 throughwhich the front surface of the sight glass is viewed, and which coverplate is secured to the casing 11 by any suitable means as bolts andnuts indicated at 18. In the space between the sight glass 10 and eachwall of the casing there is arranged a suitable packing 19. Means areprovided for keeping this packing in place without placing any unduestrain upon the other parts of the device, comprising a series of straps20 adapted to encircle the casing and provided with inturned flanges 21which are adapted to contact with and press upon compression plates 22which are inserted through apertures in the cover 17 provided for thatpurpose into the space between the sides of the sight glass and thewalls of the casing and have their inner ends in the form of acontinuous ring 22 that bears against the packing 19. A set screw 23 isadapted to pass through each strap at the rear and to impinge againstthe rear wall of the easing. A suitable packing 24. is interposedbetween the sight glass and the casing, and a further suitable packing25 is interposed between the sight glass and the cover 17.

lVhat I claim is:

1. A water gage comprising a casing provided with a water channel andside walls, a sight glass within the casing in front of said channel, anapertured retaining cover in front of the sight glass, a packing betweenthe casing and the sight glass on each side of the channel, a packingbetween the cover and the sight glass on each side of the coveraperture, a packing between the sight glass and each side wall of thecasing, and means adapted to compress the last named packing consistingof a strap adapted to encircle the casing and provided with inturnedflanges in combination with separable compression plates engaged by saidflanges and arranged between the sight glass and the side wall andadapted to contact with such packing.

2. A water gage comprising a casing provided with a water channel andside walls, a sight glass within the casing in front of said channel, anapertured retaining cover in front ofthe sight glass, a packing betweenthe casing and the sight glass on each side of the channel, a packingbetween the cover and the sight glass on each side of the coveraperture, a packing between the sight glass and each side wall of thecasing, and means adapted to compress the last named packing consistingof a strap adapted to encircle the casing and provided with inturnedflanges in combination with separable compression plates engaged by saidflanges and arranged between the sight glass and the side wall andadapted to contact with such packing, and which plates are adapted topass through suitable apertures in the retaining cover.

3. A water gage comprislng a casing provided with a water channel andside walls, a sight glass within the casing in front of said channel, anapertured retaining cover in front of the sight glass, a packing betweenthe casing and the sight glass on each side of the channel, a packingbetween the cover and the sight glass on each side of the coveraperture, a packing between the sight glass and each side wall of thecasing, and means adapted to compress the last named packing consistingof a strap adapted to encircle the casing and provided with inturnedflanges in combination with separable compression plates engaged by saidflanges and arranged between the sight glass and the side wall andadapted to contact with such packing, and means for securing the casingand cover together.

l. A water gage comprising a casing provided with a water channel andside walls, a sight glass within the casing in front of said channel, anapertured retaining cover in front of the sight glass, a packing betweenthe casing and the sight glass on each side of the channel, a packingbetween the cover and the sight glass on each side of the coveraperture, a packing between the sight glass and each side wall of thecasing, and .means adapted to compress the last named packing consistingof compression plates arranged between the sight glass and each sidewall of the casing, and means adapted to hold them in position.

5. A water gage comprising a casing provided with a water channel andside walls, asight glass within the casing in front of said channel, anapertured retaining cover in front of the sight glass, a packing betweenthe casing and the sight glass on each side of the channel, a packingbetween the cover and the sight glass on each side of the coveraperture, a packing between the sight glass and each side wall of thecasing, and means adapted to compress the last named packing consistingof compression plates arranged between the sight glass and each sidewall of the casing, and means adapted to hold them in position includinga series of straps encircling the casing and contacting with the frontedges of such plates.

6. A water gage comprising a casing provided with a. water channel andside walls, a sight glass within the casing in front of said channel, anapertured retaining cover in front of the sight glass, a packing betweenthe casing and the sight glass on each side of the channel, a packingbetween the cover and the sight glass on each side of the coveraperture, a packing between the sight glass and each side wall of thecasing, and means adapted to compress the last named packing consistingof compression plates arranged between the sight glass and each sidewall of the casing, and means adapted to hold them in position includinga series of straps encircling the casing and contacting with the frontedges of such plates, and each provided with means for securing it inposition.
